A speaker is just a confused microphone.

[Donnie B.]

It's true.
They are both technically motors/engines.
Put one thing in and get an entirely different thing out.

Speaker: feed it electricity and it produces acoustic energy.
Microphone: feed it acoustic energy and it produces electricity.

Disagree?

Nothing to disagree with, and no confusion - they're both acoustical transducers. In fact I've often used a speaker as a microphone, for example an NS10 on a kick drum.

Read about this. Something about the large and robust diaphragm (cone in this case),
being able to more accurately capture loud transients.

I use a guitar speaker for capturing bass drum. Works incredibly well.

The transient response is kinda sluggish, but the advantages are low end extension and being able to cover a large surface area. Some Beatles bass tones were created by using a bass speaker as a 'mic' on the bass cab, cool trick.

I owned a recording studio for 10 years and often guys would have the headphones so loud they'd be feeding back. Of course they'd still want "more volume" even after I'd explained the reason for the feedback!!!

LSD, Lead Singer Disease, it's a bitch.

Amen to that. A special breed of human those guys.

Feedback - the word used to describe the occasional cat fight that breaks out between
the two engines over who's the King of Transducer Mountain.
